Improvement in boilers for heating buildings



UNITED STATES THOMAS J. MYERS, or PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN BOILERS FOR HEATING BUILDINGS.

Specification forming part of Letters Patent No. 117,448, dated July 25, 1871.

To all whom it may concern:

Be it known that I, THOMAS J. MYERS, ofthe city and county of Philadelphia and Stateof Pennsylvania, have invented a'certain Improvement in Boilers for Heating Buildings, Snc., of which the following is a specication:

The invention relates to that class of boilers which is used for heating dwellings, Sac., by means of steam or hot water; and it consists of a certain novel construction and arrangement of the tubes thereof, as will be hereinafter eX- plained.

Referring to the accompanying drawing, Figure l represents a view, in perspective, of the boiler embodying my invention, Fig. 2, a longitudinal section of the same.

A A represent the side walls of the boiler. These are arranged Substantially parallel to each other, and at a suitable distance apart. They are cast or otherwise made hollow, and may have their ends inclined to their horizontal edges, as shown, or at right angles thereto, as may be desired. Each of these walls has on one side diagonal openings communicating with its hollow interior, and into or over Said diagonal openings are tted wide, oblon g, llat tubes B, extending nearly or quite the entire distance from the top to the bottom edges of the walls A, and, of course, l

arranged diagonally, as shown in the drawing, so that each shall lap its predecessor, but leave sufficient space between them through which the flame and heated products of combustion from the lire shall pass when the whole is placed in a horizontal position over the grate. E is the induction-tube through which water is introduced to the boiler, and C and D are the How-pipes. These latter are connected to the pipes which extend throughout the building, and the Water, when heated, circulates through them, and rereturning enters again at E to be reheated and returned again through the building, this system of circulation being well known to those skilled in the art.

The chief novelty of the invention, as before stated, consists in the form and arrangement of the tubes, which afford a very large extent of heating-surface, and great facility for cleaning the boiler when it may become fouled between the pipes. The flame and heated products 0f combustion rising from the grate'below strike lirst the under 'surface of each tube, and before passing entirely out at the chimney are deileoted onto the top of each also, andthus are brought into intimate contact with both sides of each tube. By the use of a suitable instrument both the top and bottom surfaces of all the tubes can be cleaned with the greatest facility.

Having thus described the construction, operation, and advantages of my invention, I claim- A boiler, having its tubes constructed inawide, oblong, iiat form, and arranged diagonally parallel and lapping each other, as described, and

for the purpose specified.

' THOS. J. MYERS.
